This species is very easily recognised by its hairy pods. Some difficulty is at 

 times found in separating flowering specimens of this from flowering specimens of 

 the next species ; the two are however quite distinct. Equally distinct are two other 

 species, D. alatum and D. pseudo-triquetrum, quite justly differentiated by De Can- 

 dolle but merged in D. triquetrum by Miquel, who has been followed in the Flora of 

 Brit. Ind. 



15. Desmodium auriculatum DC. Prodr. II, 326. A littoral shrub

 wings ; blade 3-4 in. long 1-1*5 in. wide, oblong or ovate-acute with 

 truncate or cordate base and acute apex, green and glabrous on both 

 surfaces, lateral nerves 10-12 pairs and secondary cross reticulate 

 venation distinct on both surfaces, especially beneath ; stipules large '5 

 in. long '2 in. wide, subscarious, closely parallel- veined, persistent, stipels 

 adnate to tip of petiolar wing. Lijiorescence in axillary and terminal 

 racemes 5-8 in. long, of solitary or fascicled flowers in the axils of 12-20 

 simple scarious bracts ; pedicels ascending, '3 in. long. Calyx '15
